Superconducting quantum interference phenomenon in BiSrCaCuO single crystals
arXiv:cond-mat/0508376 · doi:10.1103/PhysRevB.72.212501
Abstract
The operational dc-SQUID based on intrinsic Josephson junctions in BiSrCaCu2O high- superconductor is fabricated and studied. The novel in-plane loop layout and the developed in-situ endpoint detection method allowed an accurate control of the number of junctions in the SQUID. A clear periodic modulation of the superconducting current as a function of magnetic flux through the SQUID loop is observed. This is an unambiguous evidence for the quantum interference phenomenon in BiSrCaCu2O single crystals.
